Looks like a QuickBooks programming bug to me...

I've had the correct email address set up in the BCC field under:
Edit > Preferences > Send Forms > Company Preferences

However, when I Email an Invoice, Outlook opens with the attached PDF invoice, but the Email Send From address is not what is setup above, it's one of my other 10 email accounts that I have set up in Outlook, and it's not even the default email account I use for Outlook.

I shouldn't have to manually change the 'Send From' email address for every single invoice I want to send from Quickbooks.

Any solutions for this problem?
